This documentation provides guidelines to enhance CI/CD practices within HostSpace Kubernetes Engine, catering to DevOps engineers and platform administrators.
Best Practices
- **Implement Role-Based Access Control (RBAC)** RBAC ensures that only authorized users have access to resources, enhancing security.
- **Enable Network Policies** Network policies help secure communication between pods, adding an extra layer of security.
- **Implement Pod Security Policies (PSP)** PSPs define the conditions pods must meet to run, increasing security by restricting pod capabilities.
- **Use Horizontal Pod Autoscaling (HPA)** HPA automatically adjusts the number of pods in a deployment based on resource usage, improving scalability.
- **Implement Cluster Autoscaler** Cluster Autoscaler automatically adjusts the size of the cluster based on resource demand, enhancing scalability.
- **Set up Monitoring and Alerting** Use tools like Prometheus and Grafana to monitor cluster health and set up alerts for critical events, ensuring reliability.
- **Implement CI/CD Pipelines** Automate deployment processes with CI/CD pipelines to ensure consistency and reliability of deployments.
- **Regularly Update Kubernetes Versions** Stay up to date with the latest Kubernetes versions to benefit from security patches, bug fixes, and new features.
- **Perform Regular Backups** Back up critical data and configurations regularly to prevent data loss and ensure reliability.
- **Implement Rolling Updates** Use rolling updates for deployments to update applications without downtime, ensuring reliability and availability.
Quick Tips
-
Always use Kubernetes namespaces to logically isolate your resources:
Terminal window kubectl create namespace <namespace_name> -
Leverage resource requests and limits to manage resource allocation effectively:
Terminal window kubectl apply -f deployment.yaml -
Regularly monitor cluster health and resource utilization:
Terminal window kubectl top nodeskubectl top pods -
Implement readiness and liveness probes in your deployments to enhance application reliability:
readinessProbe:httpGet:path: /healthzport: 8080initialDelaySeconds: 5periodSeconds: 10 -
Use labels and selectors consistently for organizing and querying resources:
Terminal window kubectl label pods <pod_name> app=<app_name>kubectl get pods -l app=<app_name> -
Regularly update and patch your Kubernetes clusters for security and performance improvements:
Terminal window gcloud container clusters upgrade <cluster_name> --zone=<zone> -
Implement horizontal pod autoscaling based on metrics to automatically adjust the number of pods:
Terminal window kubectl autoscale deployment <deployment_name> --min=2 --max=5 --cpu-percent=80 -
Secure your Kubernetes cluster by following security best practices, such as RBAC and network policies:
